iam not sure if iam in the right forum section but my question is, this one section of town houses in my neighboor hood has this reddish light that is on every night you can see it when you walk in the back of the houses. Its a window in the backyard. I know this person use to grow weed and use to sell. When you walk back their during day time its like a blueish color? my question is does anybody know any lights that would do this in comparasion to growing weed? its just very weird that they have a red light on down their at night when i know for a fact nobody is down their and its on ALL THE TIME not one night when i was walking back has it been different color. friend suggested it might be a heat lamp but why would they have a heat lamp on during the summer time?? any feedback would be wonderfull thanks!
